《黑影之塔》（日文原名：影の塔，英文名：Lost in Shadow）是由Hudson Soft開發及發行，於 2010年在Wii平台推出的風格獨特的動作冒險與解謎遊戲。最大的特色在於其「影子世界」的創新玩法，不再控制實體角色，而是操縱角色的「影子」在光影投射的空間中展開冒險。這樣的概念不僅在視覺上充滿想像力，也賦予遊戲極具挑戰性的解謎與平台跳躍設計。

故事劇情圍繞著一名無名少年的影子展開。他的身體與影子被神秘力量分離，而影子被丟入高聳入雲的巨大塔中。這座塔宛如古老遺跡，環境荒涼、氣氛詭異，而少年必須一步步向塔頂攀登，尋找自己身體的所在，同時揭開塔中隱藏的秘密與過去的記憶。整個過程充滿寓意，象徵靈魂的尋找與對自我的覺醒。

操作上，操縱投射在場景物件上的「影子」。畫面中主要為橫向捲軸設計，角色只能在光線所產生的陰影上行動。這種設計使得場景中的每一個物件，無論是樓梯、機關、敵人，甚至是光源本身，都可能對影子的移動產生影響。為了解開謎題、進行跳躍與戰鬥，需不斷調整光源的位置與角度，改變陰影的樣貌與連結方式，創造出可通行的路徑。隨著冒險進展，還可以獲得名為「Spangle」的能量物質，用以強化影子的生命值與能力，例如使用劍攻擊敵人，或操作某些特殊機關。

除了影子視角的玩法之外，亦加入少量實體世界的交錯段落。在某些場景中，可以短暫控制「影子妖精（Spirits）」，移動現實世界中的物體或光源，進一步影響影子的冒險進程，這使得虛實交錯的玩法變得更加豐富有趣。

在市場評價方面，被視為Wii平台上極具創意與藝術性的作品。許多評論指出，在美術設計上呈現出低彩度、朦朧而富詩意的風格，搭配低調的環境音樂，營造出孤寂卻優雅的氛圍。尤其是在遊戲主題圍繞著「影子」、「記憶」與「自我探索」的哲學性元素上，讓人聯想到《ICO》、《Limbo》等風格遊戲。雖然在操作手感與節奏掌控上偶有不流暢之處，但其整體創意與敘事深度獲得高度肯定。

知名遊戲網站 IGN 給予此作 7.5分（滿分10分），稱其為「令人驚豔的小眾珍品」，並認為其視覺風格與解謎設計極具特色，但指出部分重複的攀登段落與略顯單調的戰鬥系統可能會影響長時間的遊玩體驗。《Game Informer》則認為是對平台遊戲傳統的一次詩意變奏，稱讚它「雖然靜謐卻充滿力量」。

總體而言，這是以創新概念與濃厚氛圍為主軸的藝術型平台遊戲，雖然並非主流市場的熱門大作，但對於喜歡獨立美術風格、愛好解謎與探索題材的玩家而言，無疑是值得沉浸的影子之旅。

Lost in Shadow (original Japanese title: 影の塔, Kage no Tō) is a uniquely styled action-adventure and puzzle platformer developed and published by Hudson Soft for the Wii in 2010. The game’s most distinctive feature lies in its innovative “shadow world” gameplay mechanic: instead of controlling a physical character, the player navigates through the game by controlling the shadow of a boy projected onto the scenery. This concept is not only visually imaginative but also introduces a refreshing take on puzzle-solving and platforming challenges.

The story centers on the shadow of an unnamed boy who has been mysteriously separated from his body. His shadow is cast down into an enormous, towering structure that reaches into the sky. The tower, which resembles an ancient ruin, is desolate and filled with an eerie atmosphere. As the boy’s shadow ascends level by level, he seeks to reunite with his physical form while uncovering the hidden secrets and forgotten memories buried within the tower. The narrative is rich in symbolism, representing a journey of the soul and a search for identity and self-awareness.

Gameplay is focused on side-scrolling platforming, where the player can only move across shadows cast by objects in the environment. The layout and structure of the stage are entirely dependent on the shapes and angles of these shadows. Everything—stairs, gears, enemies, and even light sources—affects the shadow realm and the paths that the player can take. To progress, players must strategically manipulate the position and angle of light sources to reshape shadows and create new routes. As the adventure progresses, the player collects a substance called “Spangle,” which enhances the shadow’s health and abilities, such as wielding a sword to fight shadowy creatures or interacting with special mechanisms.

In addition to the shadow-based gameplay, the game introduces occasional segments that bridge the shadow and physical worlds. In these scenes, the player can temporarily control a small entity known as a “Spirits,” which can move objects or adjust light sources in the real world, affecting the shadow world in turn. This interplay between reality and shadow adds layers of complexity and creativity to the puzzles.

In terms of reception, Lost in Shadow was widely praised as one of the most artistic and imaginative titles on the Wii platform. Critics highlighted its soft, desaturated color palette and dreamy, poetic visual style, which, together with a minimalistic ambient soundtrack, created a sense of solitude and melancholic beauty. The game’s philosophical themes—centered on “shadows,” “memory,” and “self-exploration”—drew comparisons to titles such as ICO and Limbo. While some noted that the gameplay pacing and combat mechanics could feel repetitive or sluggish at times, the overall creativity and narrative depth earned the game a warm reception.

IGN gave Lost in Shadow a score of 7.5 out of 10, calling it “a surprising niche gem,” and praised its unique visual presentation and clever puzzle design. However, the review also pointed out that the repetitive nature of some climbing sections and the basic combat might detract from extended play sessions. Game Informer described the title as “a poetic twist on traditional platformers,” applauding its quiet yet powerful aesthetic.

Overall, Lost in Shadow stands as an artistic platformer defined by its atmospheric world and inventive mechanics. Though it may not have achieved blockbuster status in the mainstream gaming market, it offers a deeply immersive experience for those who appreciate indie-style visuals, thoughtful puzzles, and introspective storytelling—a shadowy journey well worth taking.
